NCT03675698 | Completed DMC

• 1 other identifier: RES/SCM/30/2018/82
• Study Type: observational
• Target: 100
• Locations: 1 country
• Sites: 1

Brief Summary

This trial is planned to estimate the size of nasotracheal tube (NTT) by calculating the diameter of both nasal cavity in radiological images of nose (CT scan/MRI) at the level below the inferior turbinate and floor of nose in coronal planes. Smallest diameter will be considered to calculate the outer diameter of NTT, hence the size .

Conditions

Nasotracheal Tube Passage Through Nasal Cavity

Keywords

Nasotracheal tube size based on radiological images of nose.

Outcome Measures

Primary Outcomes (1)

• Successful nasal intubation by selecting the correct size of nasotracheal tube estimated by measuring the diameter of nasal cavity in coronal section just below the inferior turbinate in radiological images.

  The diameter of both nasal cavities in coronal section of CT/MRI will be calculated at the level just below the inferior turbinate in anterior nasal cavity when inferior turbinates just appeared in the radiological image, than at level of maxillary sinus and just before cohanal opening in radiological images. Minimal diameter will be used to estimate the size of nasotracheal tube before intubation.The images will also be used to select the side of nasal intubation after ruling out any nasal pathology like DNS, Spurs and marked turbinate hypretrophy.

  After enrolment of the patient and before intubation

Secondary Outcomes (1)

• To find the complications associated with nasal intubations that were performed after assessing the radiological images.

  At the time of intubation

Interventions

Nasotracheal Intubation OTHER

side of nostril and size of endotracheal tube estimation for nasotracheal intubation will be done based on radiological imaging ( CT/MRI head)

Also known as: Malinckrodt flexometallic tube
